Getting Started

In order to receive Forward messages, you can run the plugin from the command line or through the configuration file:

Command Line

From the command line you can let Fluent Bit listen for Forward messages with the following options:

$ fluent-bit -i forward -o stdout

By default the service will listen an all interfaces (0.0.0.0) through TCP port 24224, optionally you can change this directly, e.g:

$ fluent-bit -i forward://192.168.3.2:9090 -o stdout

In the example the Forward messages will only arrive through network interface under 192.168.3.2 address and TCP Port 9090.
